Digital FIR filter design using FSM
We observed that the values of Ap and As have been verified. Also we learnt that phase response is the same for low pass filter and high pass filter only if the order of both of them are identical.Frequency sampling method is more efficient computationally because many samples in the input impulse functions are zero therefore less calculations are needed.
What were the input parameters?
ReplyDeleteInput parameters were passband frequency, stopband frequency, sampling frequency, order, etc.
DeleteW1 and W2 also need to be specified for band pass or bandstop filter
FSM is a simple way of designing FIR filter
ReplyDeleteFSM method doesn't give optimum response.
ReplyDeleteWe can use windowing technique for optimum response
DeleteThe FSM TEchnique is used when the filter response is known
ReplyDeleteYes
DeleteA factor of m*(pi) is added whenever the magnitude is found out to be negative.
ReplyDeleteVery well pointed out
